Research ArticleOpen accessIn the author namesInvestigation of the Photoheterotrophic Hydrogen Production of Rhodobacter sphaeroides KCTC 1434 using Volatile Fatty Acids under Argon and Nitrogen HeadspaceRuby Lynn G. Ventura, Jey-R S. Ventura, Young-Sook OhIn this study, the photo fermentative H2 production of Rhodobacter sphaeroides KCTC 1434 was investigated using acetate, propionate and butyrate under argon and nitrogen headspace gases. The highest H2 yield and Substrate Conversion Efficiency (SCE) were observed from butyrate (8.84 mol H2/mol butyrate consumed, 88.42% SCE) and propionate (6.10 mol H2/mol propionate consumed, 87.16% SCE) under Ar headspace. Utilization of … …American Journal of Environmental Sciences, Vol. 12, Issue 6 · 30 Nov 2016 · 9,058 accessesView PDF Cite

Research ArticleOpen accessIn the author namesCarbon Dioxide Utilization for an Enhanced Biohydrogen Production of a Biomass HydrolysateAlma Negre Abug, Young Sook OhBio-hydrogen (H2) production in a thermophilic anaerobic bioreactor with carbon dioxide (CO2) utilization at the headspace was investigated at different ratio of Biomass substrate to Microorganism (B/M). A 3 mL volume of 80% NaOH (m/v) solution was continuously hung at the headspace of the bioreactors to capture carbon dioxide. The utilization of CO2 at its headspace, proved to enhance bio … …American Journal of Environmental Sciences, Vol. 12, Issue 4 · 9 Aug 2016 · 7,229 accessesView PDF Cite
